Jungle World

A Jungle World is not an official Imperial planetological classification, but is a term in common usage among Imperial citizens for those planets whose environments are a single, globe-spanning jungle across their entire surfaces. Since the term "Jungle World" is not an official Imperial classification of the Administratum but simply a label used to describe the planet's predominant environmental feature, most Jungle Worlds that have been settled by Mankind are officially classified as Death Worlds, as the environmental conditions or extant jungle biosphere are usually extremely hostile and inamicable to human life.

Notable Jungle Worlds

Planet Name	Segmentum	Sector	Sub-Sector	System	Population	Notes
Andronicus Prime	Ultima Segmentum	Jericho Reach	Unknown	Andronicus System	Unknown	Andronicus Prime is a former verdant jungle world. It was annihilated in 268.M36, when a vast city-sized vessel of unknown origin appears hurtling out of the Warp at great speed in the Andronicus system, and crashes into Andronicus Prime's second moon, shattering it. Debris rains down on the planet, blotting out the sun and laying its verdant forests waste. All life on Andronicus Prime is exterminated in a matter of days, rendering the planet into a Dead World.
Belaeno	Unknown	Unknown	Unknown	Kimmerra System	Unknown	Belaeno is a jungle world located in the Kimmerra System. While in pursuit of a Word Bearers Traitor Legion's Chaos Lord Zymran, an Ultramarines Company led by Captain Kruger receives word that the insidious influence of Chaos has begun to corrupt the population of Belaeno. Moving swiftly, the Ultramarines launch a campaign and successfully purge the Chaos Cultists as well as Zymran and his Word Bearers Chaos Space Marines.
Bengoli V	Unknown	Unknown	Unknown	Unknown	Unknown	On the jungle-covered world of Bengoli V, Bloodcrushers spearheaded a vast daemonic incursion that gutted the shrines containing thousands of Ecclesiarchy relics. Despite focused retaliation from the Catachan CXXIII, the Juggernauts proved remarkably stubborn in their efforts to smash the well concealed defence emplacements. They stomped over clusters of defenders, pushing back though Imperial lines, and forcing the Catachans to make a tactical retreat into the holy shrines. The concentration of slaughter amidst the holy relics caused a rift to open in the fabric of reality, allowing a whole legion of Khorne's followers to spill out into the material plane. So devastating was the attack on Bengoli and the scale of the invasion, that the Ordo Malleus had no option but to inflict Exterminatus on the doomed planet.
